KNITTING-MACHINE NEEDLE.

To all whom 2'2 may concern:

I a citizen of the United States of America,

residing in the city and county of Philadelphia, in the State ofPennsylvania, have invented a certain new and useful Improvement inKnitting-Machine Needles, of which the following is a true and exactdescription, reference being had to the accompanying drawings, whichform a part thereof. y I

My invention 'relates to knitting machine needles and particularly tothat kind of needles in which a butt is formed at or near the lower endof the needle shank by a fold in the metal of the shank extending at anangle to the shank. As heretofore constructed, needles of thisconstruction have proved liable to breakage at the loop formed at theend of the butt for the double reason that the metal is particularlystrained at this point and the blows of the picker and actuating camsfall upon the butt in such close relationship to the crease formed atthe end of the butt that they are peculiarly apt to produce breakage atthis point.

The object of my invention is to obviate or greatly diminish theliability of breakage of the needle butts and this I'accomplish byforming the butt with an outward extension consisting of a rolled,forged or pressed prolongation of the loop formed at its end, thishaving the double effect of relieving the strains caused by the abruptbend of the metal andby the prolongation of the butt beyond the creasecausing the blows falling fi (1 upon the needle butt to fall at a pointremoved from that which has been found to give rise to breakage.

Reference being now had to the drawings Specification of Letters latent.7 Patented Aug. 22 1916 Application filed October 4, 1913. Serial No.793,347.

-Figure 1 is an elevation of a needle or ordinary construction, and Fig.2 an elevation of a needle embodying my improve-' 7 ment.

A is the shank of the needle having a butt formed by folding the metalof the shank against itself as shown at B B, D being the loop of thisfold and C the crease formed .at the end of the butt.

A is an extension of the shank which is ordinarily recognized aspreferable.

My improved needle, as shown in Fig. 2,

has the metal of the loop D forged or pressed outwardly as shown at Dwith the result of relieving the strains formed in the loop D in theprocess of bending it and also of so extending the butt beyond thecrease C that the blows falling. upon the needle butt are measurablyremoved from said crease and less liable to cause a rupture at thatpoint.

Having now described my invention, what I I claim as new and desire tosecure by Letters Patent is,

A knitting machine needle having a butt formed by a fold in the metal ofthe shank extending outward from the shank, said butt being furtherextended by a forged or outwardly pressed blunt extension of the metalof the loop formed at its end to there by increase the ratio of thelength of the parallel side edges of the butt to thelength of thecentral fold line for the purpose speci- ROBERT WELTHALL.
